This inventionv relates to an improved wrapper or package for safetyrazor lades,

and has reference, more particularly, to a Wrapper or package especiallyadapted to enclose a plurality of tongue-ended safety raz'irV blades.

This invention has for its principal object l5 ment h ely to bring thesharpened edges ofv the bades in contact with the folds of the wrapperenclosure with risk dulling such edges, while at the same time rovidinga novel interfolding relation of said) blade hold- 2U ing sectionscalculated to segregate the blades one from another, while also assuringindividual covering protection for each blade. This invention has foranother 'object to provide a razor blade enclosing package havlng incombination interfoldable individual blade holding sections and anexternal e'nveloping cover or wrapper for the same; the

invention also has for an object to provide a novel form of bladeencloslng package of $0 the kind mentioned, from which individual bladeholdin sections may be readily removed at wil by the ultimate consumeror user of they blad This invention has for a further object to providea novel blade enclosing package which may be cheaply produced frompaper, metal foil or other suitable material.

Other objects of this invention, not atl this time more particularlyenumerated, will be understood from the following detailed descriptionof the same.

An illustrative embodiment of this invention is shown in theaccompanying drawings, in which Fig. 1 is a front face view of theclosed razor blade package or wrapper according to this invention; Fig.2 isa rear face view of the same; and Fig. 3 is a longitudinalsection,-taken on line 3--3 in Fig. 2.

' Fig. 8 is a plan view of the blank of material from which thev novelpackagev is formed.

Similar characters of reference are employed in the above describedviews, to indicate correspondin parts. A

Referring'to sald drawings, the reference character 10 indicates therazor blades adapted to be enclosed in the novel package 'of thisinvention. These blades are of the type possessing tongue-ends, that istongueportions 11 at their respective'ends of a width less than thetotal Width of the blade body. Said tongue-portions 11 form, with theends of the blade body, shoulders 12 at opposite sidesofthetongue-portions. 75 The novel blade holding and segregating means,comprises a longitudinal body of lexible material, such, for example, aspaper, metal foil, or composite paper and metal foil material or othersuitable material capable of being folded into the desired bladeholdportion and the external envelope sec'- tion. The blade holdingportion comprises a strip of material having a width in excess of thelength of the body portionof the blades 10 exclusive of thetongue-portions 11 thereof; said strip being divided by transverse foldsto provide a plurality of transverse blade holding sections 13 of widthsin excess of the Width of said blades 10, and corresponding in number tothe number of blades desired tobe assembledand enclosed Within thecompleted package. Integrally connected with the opposite ends of therespective blade holding sections 13 are in- 95 foldable aps 14. Formedin these flaps 14, with one side thereof approximately contiguous to theline of fold whereby said flaps are joined to said holding sections 13,are

rectangular openings 15 of dimensions 10c slightly exceeding thedimensions of the ton e-portions 11 of the blades 10. Exten ing alongthe lines of transverse folds intermediate adjoining blade holding sections 13 are lines of perforations 16, whereby the material is weakenedso that onebladev i, 15 is connected with one end of the blade holdingportion as au integral part thereof. Said envelop section comprises -asidewise flap section 17 intermediate its main body 18 and the inner endof said blade holding portion. Said main body 18 is provided at itsopposite end with an opposite sidewise flap section 19, and at itsrespective longitudinal sides with endwise flap sections 20 and 21.

To assemble the blades 10 with the blade holding portion of the wrapperor package structure, the blade holding sections 13 are stretched out inlongitudinal extension with the foldable iiaps 14 opened out into theplane of said sections 13. The blades 10 are thereupon respectivelysuperimposed upon the inner faces of said holding sections 13 so thatthe tongue-portions 11 of the blades register over the openings 15 ofthe extended foldable flaps 14. When the blades 10 are thus positionedupon 'the holding sections 13, the

' foldable flaps 14 are thereupon inturned over the ends of the bladebodies in such manner that the tongue-portions 11 project through theopenings 15 with shoulders 12 of the blade bodies engaged againstandwithin the folds 14 formed between said-'holding sections 13.

and said foldable flaps 14. By the'relation thus established between theblades and the holding sections 13- and their flaps 14, said blades aresecurely held both against longitudinal and lateral shifting movementsrelative to the holding sections, and since the blade Yholding sections13 and flaps 14 are wider than the extreme widths of the blade bodiesand lie over opposite faces of the bladesin planes lparallel thereto,thersharpened edges of the blades are fully protected ,f against anydirect edge-on contact with any portion of the -holding member orcovering 5 5 envelope, and consequently are not subjected to any risk ofturning or dulling.

- To enclose the assembled blades and holding sections into theenveloping external cover means, said holding sections are foldedtogether, preferably in the zig-zag fashion indicated in Figs. 6 and 7,until the same overlie one another as shown in Figs'. 3 and 4, with theblade holding section 13 at the free end of blade holding portioninturned upon the top of the pile of holding sections thus formed. Thefolded up pile of blade holding sections is inturned over and upon coverflap section 17, which is thereupon inturned overl and upon the insideface of the cover body 18, to dispose the pile of holding sectionstherebetween. With the parts thus arranged, the opposite endwise flap 20is overturned or infolded upon the flap 17, whereupon the other endwiseia'p 21 is overturned upon the infolded flap 20, and `finally theremaining sidewise flap 19 is-inturned over said fiaps 20-21. Themeeting faces of said flap sections 19-,21 are preferably adhesivelysecured together, thus firmly and securely retaining the cover means inenveloping relation to the folded up blade holding sections, or thecover flap sections may be otherwise secured in closed condition. Theouter'face of the main body 18 of the cover member may bear suitableadvertising data, trade-mark or trade-name description of the enclosedblades.

lVhile I have shown the cover means integrally connected with the bladeholding portion of thepackage, I do not desire to be limited to sucharrangement, since the cover means may comprise an independent .orseparate envelope or other form of container to receive the bladeholding portion.

It will be obvious that the user of the blades may tear open the flapsections of the cover member, whereupon by unfolding the endwise flap 17to expose the pile of blade holding sections, access may be had to theouter or end most holding section 13, which may be unfolded as indicatedin Fig. 5 and torn off, if desired, through the line of perforations 16,the contained blade removed therefrom by unfolding the flaps 14 to giveaccess thereto, whereupon the thus severed holding sec- `tion may bediscarded, and the remaining holding sections with their containedblades refolded into the cover member until another blade is required,whereupon these operations are repeated until all the blades are used.

From the above description it will be understood that a simple and yetefficient protective enclosing package for safety razor blades, andespecially blades of the tongueend type, is provided, both for use as acommercial distributing package as well as 'a container for the bladesuntil the same are used by the purchaser. In its broadest aspect, theinventionv resides in the novel foldable blade holding means per se,regardless of the association therewith of the outer cover means, whtheras an independent element or as an integral part thereof as shown; thelatter arrangement being, however, from more specific aspects a part ofthis invention for which claim is also made.

As changes other than those above indicated could .be made in the abovedescribed constructions, and many apparently widely differentembodiments of this invention could be made without departing from thescope of. this invention as herein described and shown, it is intendedthat all matter contained in the above description or shown in theaccompanying drawings shall be interpreted as illustrative and notv in alimiting sense. s

I claim 1. A foldable means for holding and individually segregating aplurality of safety razor blades of the tongue-end type, comprising astrip of material foldable transverselyto provide a plurality ofinter-connected blade holding, sections upon which blades may besuperimposed, said holding sections having widths in excess of the widthof the blades to be received thereby, yand each section 'having'oppositely projecting end flaps havlng openings adjacent the line offold thereofD through which tongue-ends of said blades may projectwhereby said blades are secured against lateral displacement relative oholding sections to which they are applie A 2. A foldable means forholding and individually segregating a Y plurality of safety razorblades of the tongue-end type, comprising a strip of materia-l foldabletransversely to provide a plurality of interconnected blade Aholdingsections u on which blades may be superimposed, ,sai holding sectionshaving-v Widths in excess of the width of the blades to be receivedthereby, each section having oppositely projecting end' iaps havingopenings substantially contiguous to the line of fold thereof throughwhich tongue-ends of said blades may project so as to be secured againstboth lateral and longitudinal displacement relative to holding sectionsto which they are applied, and an external cover means connected withone end of said strip of material, said cover means comprising a mainbod sidewise foldable flaps at each side of sald main body, one of saidsidewise foldable flaps being foldably connected to the end of saldstrip of material forming said blade holdin r sections, and endwisefoldable flaps connected respectively with the opposite ends ofl saidmain body.

In testimony, that I claim the invention set forth above I have hereuntoset my hand this 22nd day of April 1931.
